Another interesting fact is that the tires are rated for 2409lbs per tire, so the RAWR of 4050 lbs is 768 lbs below the tire ratings. Looks like Ford is putting firm backing behind the axle ratings by putting them so close to the GVWR.
Great observation Russ...
thanks!

Ford knows their required by fed 571 FMVSS which says;
" When a passenger car tire is installed on a multipurpose passenger vehicle, truck, bus, or trailer, the tire's load rating shall be reduced by dividing by 1.10 before calculating the sum (i.e., the sum of the load ratings of the tires on each axle,".
Even derating per the FMVSS the tire still has plenty of capacity for a 4050 axle rating.
The OP has a very capable truck for its size and is one of the new gen 1/2 to and 3/4 ton and one ton SRW trucks with the GVWR real close to the sum of the axle ratings.
